[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0020] according to Figure 1-4 As shown, this embodiment provides a nursing patch for blunt needle puncture, comprising a protective gear component 1 and an inner protective gear component 4, wherein a tightly fitting filling component 2 is arranged on the inner side of the protective gear component 1, and a sleeve-mounted fixing member 3 is arranged on the outer side of one end of the filling component 2, and a tightly fitting inner protective gear component 4 is arranged on the inner side of the filling component 2;

[0021] The inner protective kit 4 includes a rubber layer 401, a needle base 402, an upper cover 403 and a pull rod 404. The rubber layer 401 is arranged on the inner side of the filling component 2, the needle base 402 is arranged on the inner side of the rubber layer 401, the upper cover 403 which is adhesively connected is arranged above the rubber layer 401, and the pull rod 404 is arranged above one side of the upper cover 403.

[0022] The rubber layer 401 and the needle base 402 form a concentric annular structure, and the needle base 402 has a porous structure.

[0023] In this embodiment, the upper cover 403 is then removed through the top of the upper cover 403 and the pull rod 404, and then a blunt needle is used to pierce the patient's blood vessel using the needle base 402 on the inner side of the rubber layer 401.

[0024] The protective gear assembly 1 includes a waterproof film layer 101 , an outer patch 102 , a rubber layer 103 , adhesive tape 104 and an easy-pull strip 105 . The outer patch 102 is arranged below the waterproof film layer 101 , and the rubber layer 103 is arranged below the outer patch 102 .

[0025] In this embodiment, after the adhesive tape 104 is torn off, the medical staff uses the waterproof film layer 101 and the outer patch 102 to stick the product on the patient's affected area under the action of the adhesive layer 103.

[0026] An adhesive tape 104 is provided on one side of the adhesive layer 103 for bonding, and an easy-pull strip 105 is provided below one end of the adhesive tape 104 .

[0027] In this embodiment, when in use, the adhesive tape 104 is torn off through the adhesive layer 103 by means of the easy-pull strip 105 below one end of the adhesive tape 104 .

[0028] The filling component 2 includes an outer shell 201, an inlet tube 202, a rubber plug 203 and a coating area 204. The outer shell 201 is arranged on the inner side of the outer patch 102, an inlet tube 202 is arranged on one end of the outer shell 201, and a rubber plug 203 is arranged on the inner side of one end of the inlet tube 202, and the inner cavity of the outer shell 201 is provided with a coating area 204.

[0029] In this embodiment, a syringe is then used to inject physiological saline into the drug application area 204 inside the outer shell 201 through the rubber stopper 203 at one end of the inlet tube 202 .

[0030] The fixing member 3 includes a sleeve 301 , a strap 302 and a Velcro 303 . The sleeve 301 is arranged on the outer side of the inlet tube 202 , and straps 302 for installing the Velcro 303 are arranged on both sides of the sleeve 301 .

[0031] In this embodiment, after the blunt needle pierces the patient's blood vessel, the blunt needle is fixed using the straps 302 and Velcro 303 on both sides of the tube sheath 301, and then stuck to facilitate subsequent effective treatment operations.

[0032] The working principle of the nursing patch for blunt needle puncture is as follows: when in use, the adhesive tape 104 is torn off through the adhesive layer 103 by the easy-pull strip 105 below one end of the adhesive tape 104. After the adhesive tape 104 is torn off, the medical staff uses the waterproof film layer 101 and the outer patch 102 to stick the product on the patient's affected part under the action of the adhesive layer 103, and then uses a syringe to inject physiological saline into the coating area 204 inside the outer shell 201 through the rubber plug 203 at one end of the inlet tube 202, and then removes the upper cover 403 through the top of the upper cover 403 and the easy-pull strip 404, and then uses a blunt needle to pierce the patient's blood vessel using the needle base 402 on the inner side of the rubber layer 401. After the blunt needle pierces the patient's blood vessel, the straps 302 and Velcro 303 on both sides of the tube sleeve 301 are used to fix the blunt needle, and then stick it, so as to facilitate subsequent effective treatment operations.
